Title: Air cap for enamel-ceramic glass spray gun - with tangential sec. gas source to improve conditions of sputter or spray beam
IPC: B05B7/08
Filed: 1989-07-10
Abstract: Air cage for fitting onto the end of an enamel and ceramic glass spraying pistol has a stepped conical inner dia. with a third section (5) having inclined grooves to produce a rotating movement in the prim. drive gas as it emerges with the spray material from the nozzle exit (6). A sec. drive gas is directed inwardly (12) towards the spray beam so it tangentially touches the beam. Oppositely arranged projections touches the beam. Oppositely arranged projections (10) through which the sec. gas flows are each directed towards the main beam so they run parallel to each other on opposite sides of the main beam and spaced apart by a distance (2d). USE/ADVANTAGE - Esp. spraying lacquer and heavy material e.g. enamel and ceramic glass. Tangential sec. gas effect ensures a min. amt. of mist prodn. A low drive gas and material-pressure can be used. The material is well dispersed to give a good sputter and spray beam effect.

Title: Hermetically sealed circuit for driving rotary piston motor - contg. heated mixt. of liquefied gas and lubricant oil
Inventor: SCHMITZER WILLI
IPC: F02G1/04
Filed: 1989-08-14
Abstract: The sealed heating circuit for the lower and medium temp. ranges comprises an evaporator (1), a spray jet (2), the rotary piston motor (3), a condenser (4) and a pump (5). The circuit is filled with two different fluids, e.g. a liquified gas and a lubricant oil with each function space held at the pressure of the liquified gas. Pref, the fluid mixt is heated externally within the heater so that the liquidfied gas is vaporised while the lubricant oil remains in the liquid phase. Pref., the lubricant oil is fed to  the rotor bearings (8)via a regulating valve (7). Because of the flammable fuel no rotary shaft must projectoutside. Hence inside the system, an electromagnetic armature is coupled to the rotors.  A.c. is induced in an external starter via a thin anti-magnetic cylinder. ADVANTAGE - Effective lubrication.

Title: Addn. of initiators to polymerisation systems - by introducing the initiators into a water-filled feed pipe and gradually injecting them into the reactor over 20 minutes using water
Inventor: NAKAMURA TATSUMI
IPC: C08F2/16
Filed: 1990-11-12
Abstract: A process is claimed for the addn. of a polymerisation initiator (I) for the aq. suspension or emulsion polymerisation of monomers; and involves introducing (I), which is active at relatively low temp., into the pipeline which is prefilled with water and then gradually introducing the initiator into the polymerisation system in 20 mins., using water. (I) is introduced into the polymerisation system at room temp.; (I) is metered into the water-filled pipeline and transferred to the polymerisation system with water; several types of initiators are fed into a single feedpipe for the system; after the initiator is added to the pipeline, a solvent is added which is soluble in both the initiator and in water, and which has only a slight effect on the polymerisation system, and the initiator is then transferred as above. The initiator is transferred to the system via a single pipe which is fitted with a nozzle for spraying water (pref. pure water at not above 30 deg.C) into the pipe in  order to remove any blockages and lower the temp. inside the pipe.  The process is applied to the suspension or emulsion polymerisation of vinyl chloride (VC), copolymerisation or graft copolymerisation of VC with comonomer(s), radical chain polymerisation of styrene, (meth)acrylic acid and esters thereof, and vinylidene chloride, and copolymerisation of these monomers with other comonomer(s). ADVANTAGE - The system is less expensive, w.r.t. equipment and energy costs for cooling, than prior-art double-tube system (esp. if several different initiators are added); only water is left in the feed pipe after the initiator is transferred, thus reducing the potential hazards (contrast prior-art systems). The initiator can be pumped into a closed reactor under pressure if required and the prod. is of better quality (fewer fish eyes, etc.).
